Abstract:
Physicochemical changes could affect the quality of goat milk yoghurt. Yoghurt quality has been improved by incorporating a synbiotic derived from a prebiotic combined with probiotics. This study aimed to evaluate the effect of different concentrations of synbiotics (inulin of mangrove apple and Lactobacillus plantarum) in the physicochemical properties of goat’s milk yoghurt. This study used a Completely Randomized Design (CRD) with 5 treatments and 4 replications, with differences in the concentration of synbiotics as much as 0, 2, 4, 6, and 8%. The addition of synbiotics was significant (p < 0.05) in the sugar reduction, colour, and syneresis of yoghurt products. They did not significantly affect (p > 0.05) the firmness of yoghurt texture. This study provides support for the addition of synbiotics to improve physicochemical properties of goat’s milk yogurt.
